Description
Overview:
The Main Bearing 020 Pair for Lister HR engines is a matched set of half-shell main bearings that support the crankshaft and maintain correct oil clearance for smooth, efficient running. Supplied as a Genuine Lister Petter part, these shells are manufactured from high-quality bearing materials with precision-finished surfaces to reduce friction and wear under load. The 020 size is commonly understood to indicate 0.020 in (approx. 0.51 mm), typically used after crankshaft regrinding. Suitable for Lister HR series diesel engines, this pair is ideal for maintenance and restoration where accurate fit and durability are essential. As unused old stock, the bearings may show cosmetic tarnish from storage, but they remain fully serviceable. OEM reference: 352 50620/020 for direct replacement.
